Unable to start the service FIM Synchronization Service.Getting error "EventID:7024 - The forefront identity manager synchronization service service terminated with the following service-specific error :%%2149778515"

Hi ,

    I am trying to start synchronization service. But I am unable to start the "Forefront Identity Manager Synchronization service."

When i checked in Event Logs, an error with Errror code : 7024 "the forefront identity  manager synchronization service service terminated with the following service-specific error :%%2149778515".

I have checked SQL server service and User profile service. Both are up and running.

Please help me out.

Thanks

Praveen
